For the record (mail archive): I tried updating to the latest BIOS for
this server today, some 6 weeks later. Now it boots a SMP kernel with
acpi just fine:

(..)
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
 cpu0 (BSP): APIC ID:  0
 cpu1 (AP): APIC ID:  1
MADT: Forcing active-low polarity and level trigger for SCI
ioapic0 <Version 1.1> irqs 0-23 on motherboard
ioapic1 <Version 1.1> irqs 24-27 on motherboard
ioapic2 <Version 1.1> irqs 28-31 on motherboard
acpi0: <PTLTD    XSDT> on motherboard
acpi0: Power Button (fixed)
acpi0: Sleep Button (fixed)
(..)

I get some error messages like "unknown: I/O range not supported"
though.

I had the SMP+acpi problems with this set of BIOS/firmware versions:

$ inventory get software

While this (which I am using now) seems to work fine:
